Coal Mill Processing
Coal mill is major gear of cement plant and used for drying and grinding coal. The gear is primarily consisted of feed system, major bearings, rotating parts, drive system, promoting device, excessive-voltage start-up system and lubrication system. The raw material is fed into mill by feeding gear. The hot wind enters into the mill by inlet end. Because the mill cylinder rotates, the coal and hot air trade heat within the mill. The coal is crushed and grinded within the mill. When the coal is being grinded, the powder is introduced out of the mill by the new air going by the mill.
The coal mill we make is with reasonable construction, high grinding effectivity and is the perfect gear for coal processing. Ball grinding mill is the early coal mill used in coal powder plant, there are two sorts, wet ball mill and dry ball mill. This type coal mill efficiency is moderately good:
the output is high
the maintenance is pleasant
the operation is simple
safety management of this coal mill
Vertical mill is the most typical coal mining equipment in milling plant, so vertical mill can also be called vertical coal mill, it set up the coal mill stardard. Raymond mill can be the early coal mill, the capacity of this coal mill could be up to 6-8 t/p. The finess of the finished product will be adjusted from 100 mesh to 325 mesh according to the requirements. SBM is a professional coal mill manufacturer in China, and supply coal mills on the market with finest worth all over the world. We can also design coal mill in accordance with the particular necessities of our clients. Coal mill course of Coal is mined by explosion, then crushed by coal crusher into small items. In this coal crushing course of, several sorts of coal crusher are used. Jaw crusher, impression crusher, cone crusher can be utilized as coal pulverizer. After crushing, small items of coal enter into the coal mill for grinding. Often a whole coal milling line consists of coal mill, impulse mud cleaner, piping gadget, cyclone collector gadget, classifier. The stones are squeezed by roller and ring into powder, the powder is collected by cyclone collector. With a purpose to ptotect the surroundings, we additionally install the cloth deduster. Improper operation of the coal mill might cause the explosion of the machine . What is the right methodology to operate coal mill to avoid the catastrophe? 1. change the piling technique of the coal to make the coal accumulate little ; thus keep away from the spontaneous combustion
of the coal .
- change the gap of the grate bar from 25mm to 22mm; thus lower the wind speed and improve the drying velocity .
- add a settling chamber between the coal mill and the pipe; thus stop the new coal powder enter the coal mill .
- add a explosion-proof valve on the opening .
- enhance the fineness of the coal from 10% to 15% .
- make up strict security rules .
If the coal mill stops for 3 days, empty the coal hopper or put a layer of uncooked meat powder on the surface to isolate the coal from the oxygen earlier than stopping the coal mill, shut the recent wind valve and open the close wind valve after which stop the feeding. remember to empty the coal in the coal mill before stopping the machine and not to stop the collector immediately .
Test the following issues when operating the coal mill: the airing is ok; there isn’t a overfeeding or underfeeding; the temperature isn’t too excessive; the order of starting and stopping the coal mill is correct; the temperature of the air from the coal mill is greater the dew point.
Make an emergency plan; when an explosion occurs, close the new wind valve and the pneumatic valve, stop the new coal powder enter the collector and if the temperature is over 80 diploma centigrade, start the carbon dioxide extinguisher.
we must always concentrate to avoid security problem in working the coal mill. so long as we obey the security guidelines, the safety issues surely will be prevented.
